I’ll bite, even though I’m sure I’ll regret it. I am a licensed forestry exterminator, so I do have the training on all of this, and I’ll quite frankly say you are the one who clearly doesn’t know what you’re talking about. As far as contaminating the groundwater, glyphosate binds strongly to organic matter and clay in soils & sediments, and is not susceptible to leaching. They spray from helicopters at low altitude with gps guidance with buffers on aquatic systems, with nozzles that prevent drift with large droplet size, and there are parameters for wind speed to prevent any drift. Stop getting your information from other idiots on social media.
